NFL Stadiums Swap Grass for Turf Amid Player Safety Concerns

The NFL is converting numerous stadiums from natural grass to synthetic turf to cut maintenance expenses and boost game speed. Players argue the harder surface could raise slipping incidents and increase the risk of knee and ankle injuries.

Player unions have called for safety assessments and demanded improvements to the new playing fields. League officials, however, stress long‑term cost savings and say the transition will proceed.
